10.9.
Rendering and user-agent behavior

This section will probably include details on
how to render DATAGRID (including its
pseudo-elements ), drag-and-drop, etc, in a visual medium,
in concert with CSS. Terms that need to be defined include:
sizing of embedded content

CSS UAs in visual media must, when scrolling a page to a
fragment identifier, align the top of the viewport with the target
element's top border edge.

must define letting the user "obtain a physical form(or a representation of a physical
form)" of a document (printing) and what this means for the
UAUA, in
particular creating a new view for the print media.

Must define that in CSS, tag names in HTML
documents, and class names in quirks mode documents, are
case-insensitive.

10.1.9.1
Rendering and the DOM

This section is wrong. mediaMode will end up
on Window, I think. All views implement Window.

Some user agents may support multiple media, in which case there
will exist multiple objects implementing the
AbstractView interface. Only the default view
implements the Window interface.
The other views can be reached using the view attribute of the UIEventinteface,interface, during event propagation. There is no
way currently to enumerate all the views.

10.2.9.2
Rendering and menus/toolbars

10.2.1.9.2.1
The 'icon' property

UAs should use the command's Icon as the default generic icon
provided by the user agent when the 'icon' property computes to
'auto' on an element that either defines a command or refers to one
using the command attribute,
but when the property computes to an actual image, it should use
that image instead.
